/**
 * Semantic Analysis Hooks for glin-profanity
 *
 * Provides hooks and utilities for combining profanity detection with
 * semantic analysis using embeddings. Useful for advanced content moderation
 * that goes beyond keyword matching.
 *
 * @example
 * ```typescript
 * import { createSemanticAnalyzer } from 'glin-profanity/ai/semantic';
 *
 * const analyzer = createSemanticAnalyzer({
 *   embeddingProvider: async (text) => {
 *     // Your embedding provider (OpenAI, Cohere, etc.)
 *     const response = await openai.embeddings.create({
 *       model: 'text-embedding-3-small',
 *       input: text,
 *     });
 *     return response.data[0].embedding;
 *   },
 * });
 *
 * const result = await analyzer.analyze('This is a test message');
 * console.log(result.combinedScore); // 0.0 - 1.0
 * ```
